I'm visiting Marrakech, Morocco in a couple days and would very much not like to stand out as a tourist that much. I know all the standard "don't-look-like-a-tourist" behaviors of memorizing the maps, not flipping open the guidebook, learning a few phrases of the local language. For morocco - I'll be wearing jeans. Should I wear khakis? Any other tips or suggestions of what I should do/see? I'm grabbing a guidebook to read on the plane and perusing wikitravel already. I'll be arriving on Sunday and don't really have a timelimit (except to get back to Madrid by the 15th to catch my flight home) or specific plans. FYI - I'm a 23 year old college student.

Thank you in advance!
